The six Ash hat Pikachu in Pokémon Sun and Moon

A code to obtain Ash hat Pikachu will be revealed on the official Pokémon site. Additionally, details on the publication of a QR Code to obtain the movie hat Pikachu in Pokémon Ultra Sun and Ultra Moon have been revealed.

On September 19, 2017, a common code will be published on the official Pokémon site to obtain Ash hat Pikachu in Pokémon Sun and Moon. There are six different possible hats, and the moves Pikachu knows will vary with its hat; when the player redeems the code will determine which hat they obtain. The code can only be redeemed once per save file, so each player can only obtain one of the six different hats. The dates for each hat are as follows:

The 20th Pokémon movie, Pokémon the Movie: I Choose You!, will air in theaters in the United States and Europe on November 5 and 6, 2017. In Australia and New Zealand, the movie will show in theaters beginning November 11, 2017. A new teaser trailer for the movie has been published.

A QR Code to obtain "I Choose You" hat Pikachu in Pokémon Ultra Sun and Ultra Moon will be given away at showings, as will a TCG card featuring the same Pikachu. This has been announced by both the US site and the UK, French, German, Italian, and Spanish sites. Tickets are now available for preorder in the United States.
